L - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30
So Lane has 3 years old and Mel has 30 years old.
Answer:
115 m
Step-by-step explanation:
4 + 9 + 6 + 4 = 23 cm
23 x 5 = 115 m
This is the construction of a perpendicular line to the given line AB using a point F, which does'not lies on the line AB.
The first two steps are constructed. We have to give the next two steps to complete the construction.
Step 3: Using the same radius A and B as centers, draw two arcs below the line AB.
Step 4: The two arcs will intersect at a point. Name that point as 'X'. Join 'F' and 'X'.
Thus, FX is the required perpendicular to the line AB from point 'F'.
Hello,
The answer to this question would be B. A right scalene triangle is a "Triangle" that has a right angle into it.C would not be the answer b/c is has an obtuse angle,and So does D. So the answer is not D,So dont pick D b/c I see that you have it marked.
Hope this helps
